Computing continuous dynamic time warping of time series in polynomial time

Journal of Computational Geometry
Dynamic Time Warping is arguably the most popular similarity measure for time series, where we define a time series to be a one-dimensional polygonal curve.

Multi-modal gesture recognition with voting-based dynamic time warping

International Journal of Advanced Robotic Systems, 2019
Gesture recognition has remained a challenging problem in the fields of human robot interaction. With the development of depth sensors such as Kinect, different modalities become available for gesture recognition while its advantages have not been fully ...

Pairwise dynamic time warping for event data [PDF]

Computational Statistics & Data Analysis, 2014
We introduce a new version of dynamic time warping for samples of observed event times that are modeled as time-warped intensity processes. Our approach is devel- oped within a framework where for each experimental unit or subject in a sample, one observes a random number of event times or random locations.

Enhancing Nearest Neighbor Classification Performance through Dynamic Time Warping with Progressive Constraint

Proceedings of the International Florida Artificial Intelligence Research Society Conference
Dynamic time warping (DTW) is a widely used metric for comparing time series data, offering elasticity in alignment. While the original DTW allows infinite elasticity without penalty, the wDTW imposes a constant penalty regardless of elastic length.

Subsequence Join in Streaming Time Series under Dynamic Time Warping

Vietnam Journal of Computer Science
Subsequence join in time series is to search for couples of similar subsequences from multiple time series. The task is useful in data mining on time series; nevertheless, it is extremely difficult because of its enormous computational cost.

A Closed-loop Detection Algorithm Based on Dynamic Time Warping

Kongzhi Yu Xinxi Jishu, 2021
In the research of closed-loop detection, algorithms based on single image matching are drawing great research interests. However, in dynamic environment, such algorithms can not meet the requirements of dynamic detection.Considering that a single image ...

Efficient search of the best warping window for Dynamic Time Warping [PDF]

, 2018
Time series classification maps time series to labels. The nearest neighbor algorithm (NN) using the Dynamic Time Warping (DTW) similarity measure is a leading algorithm for this task and a component of the current best ensemble classifiers for time series.

Pronunciation Scoring With Goodness of Pronunciation and Dynamic Time Warping

IEEE Access, 2023
The current pronunciation scoring based on Goodness of Pronunciation (GOP) uses posterior probabilities of the Acoustic Models. Such algorithms suffer from generalization since they are utilized to determine a score metric for each phoneme rather than on

Correlation Based Dynamic Time Warping for ECG Waveform

Applied Sciences
Electrocardiogram waveform delineation is a fundamental task for quantitative cardiac analysis, yet accurate and consistent estimation of waveform boundaries remains challenging due to heart rate variability, inter-subject morphological differences, and ...
